Designed for installation within fire resistive joints with up to 2 hours F rating, RectorSeal Blaze Foam provides dynamic movement with up to 50% compression (see UL systems) and 100% extension capabilities for max joint width 1/4″ to 1″.
RectorSeal Blaze Foam is simple to install for head of wall applications. Compress the Blaze Foam into the joint between the top of the wall and bottom of the deck so that the intumescent strip is facing the wall surface. RectorSeal Blaze Foam can be recessed into the joint or installed flush with the outside surface of the wall. Joints are butted together. No mechanical fastening of Blaze Foam is required.
